2003-02-17  Ranjit Mathew  <rmathew@hotmail.com>

	* java/util/Properties.java (store): Move the code formerly in
	list(), into this method.
	(list (PrintStream)): Just call list (PrintWriter) with a
	PrintWriter object constructed from the given PrintStream object.
	(list (PrintWriter)): Emulate the output of Properties.list()
	as found in JDK 1.3/1.4.
